Optical trap** describes the interaction between light and matter to manipulate micro-
objects through momentum transfer. In the case of 3D trap** with a single beam, this is …

Materials with relatively small refractive indices (n< 2), such as glass, quartz, polymers,
some ceramics, etc., are the basic materials in most optical components (lenses, optical …

Inspired by the swimming of natural microorganisms, synthetic micro‐/nanomachines, which
convert energy into movement, are able to mimic the function of these amazing natural …

Optical trap** and manipulation of micrometre-sized particles was first reported in 1970.
Since then, it has been successfully implemented in two size ranges: the subnanometre …

Nanoscale surface texturing, drilling, cutting, and spatial sculpturing, which are essential for
applications, including thin-film solar cells, photonic chips, antireflection, wettability, and …

Laser processing implies the generation of a material function defined by the shape and the
size of the induced structures, being a collective effect of topography, morphology, and …

Dielectric microelements with circular symmetry have shown interesting optical properties:
photonic nanojets (PNJs) and whispering gallery modes (WGMs). They can confine light …

Non‐Gaussian beam profiles such as Bessel or annular beams enable novel approaches to
modifying materials through laser‐based processing. In this review paper, properties …

Dielectric microspheres with appropriate refractive index can image objects with super-
resolution, that is, with a precision well beyond the classical diffraction limit. A microsphere is …
